The authers report a case of malignant skin tumor in the right leg followed by old burn scar. This case was reconstructed by distally based sural flap combined with venous switching method and favorable result was obtained.A 81-year-old male patient received a contact burn at his right leg 30 years ago by hot water tank for leg warming. Erosive lesion was observed from Aug., 1995 at the scarred area. He was referred to us by his family doctor.A biopsy was performed before the operation and the result was basosquamous cell carcinoma. Radical tumor excision was carried out and the skin defect was reconstructed with a distally based sural flap whose small saphenous vein was anastomsed to the great saphenous vein at the proximal side of the defect for obtaining the normal venous cirulation.Six months had elapsed and no recurrence was observed.
